Klipsch R-40M Overview
90 X 90° Tractrix Horn
The Klipsch exclusive Tractrix horn technology delivers the power, detail, and emotion of the live music experience with clean, natural sound. The increased outer horn dimensions allow for directivity control over a larger bandwidth of frequencies, resulting in improved high-frequency directivity and a more accurate sound stage than previous models.
Linear Travel Suspension (LTS) Aluminum Tweeter
The Klipsch Linear Travel Suspension (LTS) minimizes distortion for enhanced, detailed performances. Aluminum is an extremely light and rigid material used in the tweeter assembly to provide high efficiency and improve resolution and detail. LTS tweeters are a hallmark of Klipsch speakers, making it a core component of the Klipsch design.
Spun-Copper Thermoformed Crystalline Polymer (TCP) Woofers
Utilizing trickle-down technology from Klipsch's Reference Premiere series, the TCP woofers have steeper angling of the cones for a smoother response and improved accuracy and transparency. The additional ribbing increases the overall rigidity for less cone breakup at higher frequencies.
High-Quality Cabinet Design and Appearance
Hidden fasteners, edge-to-edge horn, and low-profile magnetic grilles give the speakers a polished, modern appearance. The reinforced 3/4" MDF construction with bracing design reduces cabinet vibration for less audible coloration and improved sonic accuracy.

Klipsch R-40M Reviews
Replaced Klipsch Quintet Mains
By Christopher
Rated 5 out of 5
Date: 2026-03-09
Although these dwarf the Klipsch Quintet mains, I today received these (quickly and pristinely, thank you B&H!) and I promptly mounted them in my theatre space using the same 1/4-20 studs as the Quintets. The old mains have now become rear surround in a 7.1 theatre sound stage, upgrading the system from 5.1. The system now can really keep up with live concert video, movies, and music listening in 2.1 stereo. I am really happy with this upgrade! These speakers sound terrific for their size. I enjoy the added mid punch from the 4" woofers and the rich fullness from the cabinets. Wonderful change! I couldn't be happier.
